Hyperthermia Efficiency of Hydrothermal Synthesized Iron Sulfide Magnetic Nanoparticles

Abstract

The hydrothermal technique was used to prepare iron sulfide magnetic nanoparticles using FeCl3⋅6H2O, thiourea, and ethylene glycol as precursors. The hydrothermal process was accomplished on a hot plate at 320°C for 18 hours. X-ray diffraction (XRD) confirmed the production of iron sulfide with three phases. The dominant phase was (Fe3S4) greigite (67%) having a saturation magnetization of 9.1 emu/g. Scanning electron microscope (SEM) images approved the creation of nanoparticles with a mean diameter of 36.24nm. Alternating coil current amplitude of 100A and the frequency of about 100kHz were exerted on the sample to accomplish the hyperthermia test. Using a shallow concentration of magnetic nanoparticles, 20μg in 1.5ml of distilled water, produced a specific loss power (SLP) of about 3548 W/g. The produced particle sizes were suitable for producing good SLP value compared to the literature due to their magnetic hysteresis loss.
